Method and system for handover based on radio resource allocation database
First Claim
1. A method for handover based on a radio resource allocation database, wherein the radio resource allocation database is constructed and dynamically maintained, and the method comprises:
- after receiving a handover request from a User Equipment (UE), determining in the database, by a Base Station (BS), a Radio Access Technology (RAT) and corresponding carrier frequency resources suitable for a current communication condition of the UE for the UE according to a handover reason in the handover request, and notifying the UE of information regarding the determined RAT and information regarding the corresponding carrier frequency resources; and
performing, by the UE, Quality of Service (QoS) verification on the RAT and the corresponding carrier frequency resources notified by the BS, and switching to the corresponding carrier frequency with the RAT notified by the BS when the QoS on the RAT and the corresponding carrier frequency resources is superior to that of current communication.

Abstract
The disclosure discloses a method for handover based on a radio resource allocation database. The method includes that the radio resource allocation database is constructed and dynamically maintained; after receiving a handover request from a User Equipment (UE), a Base Station (BS) determines in the database a Radio Access Technology (RAT) and the corresponding carrier frequency resources suitable for a current communication condition of the UE for the UE according to a handover reason in the handover request, and notifies the UE of information regarding the determined RAT and information regarding the corresponding carrier frequency resource; and the UE performs QoS verification on the RAT and the corresponding carrier frequency resources notified by the BS, and switches to the corresponding carrier frequency with the RAT notified by the BS when the QoS on the RAT and the corresponding carrier frequency resources is superior to that of current communication. Meanwhile, the disclosure further discloses a system for handover based on a radio resource allocation database. The disclosure improves a resource usage rate and the QoS of a current communication system. The disclosure enables the UE to complete the handover quickly, such that user experience is improved.
